shackle connection, which will ,require little or no attention in. use,eliminate the usual problems of lubrication, and which in operation'willnoiselessly cushion vibrations, road shocks or the like.'

A further and important object of the .1nventionv is to provide aresilient mounting which will'readily yield to permitrel-ativemovement-of the spring and frame in a longitudinal direction, but willbe resistant to the highly objectionable side sway between the parts. ll Y Other objects and advantages will be ap-y parent fromthe followingdetailed specification'A of a vpreferred 'embodimentof the invention,'taken in' connection with the accompanying drawing, in which- Figs. 1and 2 are detailviews, partly in section'and partly inelevation,vshowing respectivelythe connections between opposite ends of the rearspring with the chassisframe.

Referrin more specifically to the drawing, the re erence character 1represents one of the longitudinally extending channeled` side membersof the 'chassis frame, which terminates at its rear end in ahornordownturned` portion 2, and 3 indicatesl a semi` elliptical multideafspring to flexibly support the frame4 on the rear axle. While referenceherein is only made-toene of the rear s rings, it will be obvious thatthe same shac e connections are for use with each of the vehiclesprings, both at .the front and the rear. i j

The driving connection for the front end' of the spring 3 is(illustrated in Fig. 1, which constitutes a. pivotal mounting therefor.In this case, there is provided a block of vcushioning material,preferably lconsisting of a- Y body of rubber or other elastic substance4, having integrally lembedded therein by vulcanization or the like,alink or strap 5` of flexible, .but inextensible material, such as:fabricj: thlor brous material, or if desired,

` vthis s'tfra'pfiinay be formed of thi'n sheet metal haying acomparatively high degree of resillency. A retainer cup 6, pressed orstamped from sheet metal, is riveted or bolted a nut 9: Spacedlongitudinall 1927. Serial No. 173,384.

at 7 to the bottom flange ofthe channel frame member 1,#and thecushioning block is contained within this cup, and may be placed ytherein under a slight initial compression.

The dexible strap 5 is bowed upwardly, due either to preforination ordeformation 'of the block within the cup, and a fastening bolt 8 passesupwardly through the block at the bight of the bowed strap and issecured to the bottom flange of the frame member 1 by on either side ofthe bolt 8 are fastening olts lil-10' extending downwardly through theblock at opposite ends of the strap 5,-being secured to the front end ofthe spring -3 by nuts 11-l`1.

provides a link between the spring and frame, which, since it isinextensible, does not permit side sway or relative ltransverse movementbetween the longitudinally spaced. fastening bolts. -Howeven the bow orVlongitudinal undulation in the strap allows its inherent flexibility toact in a longitudinal bottom of the horn ,2, is provided at either endwith an in-turned ear or channel portion 14 into which channels areinserted ribs or beads 15 of the resilient block. The elastic cover 16,surrounding the bowed or undulating strap 17, extends beyond the ends ofthe strap for some distance, and .is preferabl provided with transverseopenings 18, whic serve to increase its elasticity and facilitatelongitudinal distortion. The fasteningbolt 19 extends-through the blockat the bight of the strap 17, and is secured to the spring end The strap5 Within its elastic envelope 4 thusy by nut 20. Here again, the bowedstrap'l'( reinforces the block against sidesway, but readily yields orflexes with the longitudinal distortion of the elasticbodv 16. upondeection and extension of the vehicle spring 3.

While the subject matter has, vdescribed more or less specifically"inits'l preferred. form, it is to be understood that the invention is notlimited tothe exact details set forth, but that such modiiications maybe ya chassis frame and a vehicle spring, of flexible connectionsbetween the ends of the spring and the frame, including elongated blocksof elastic material, longitudinally undulated fabric reinforcementstrips lembed ded within the material, retainers for said blocks.carried by one of the members to be connected, and 'fastening boltsextending through the blocks and passing through both the elasticmaterial and the'embedded fabric and secured to the other of saidmembers to be connected.
